背景描述：电路板产品在潮湿环境中运行几个月后，发现有些电路板功耗增大，产品有IP68防潮等级。<br />问题：经仔细查找发现电路板有处两过孔及走线非常近，导致两线有电流通过，从而功耗增大，现在电路板提供商认为是受潮导致两线有电流通过，请问有什么方法可以评估电路板受潮影响，或者你们能对电路板过孔和走线作评估吗？希望尽快回复，谢谢！<img src=‘/uploadfiles/image/20210818/1629257535884085574.png’ title=‘1629257535884085574.png’ alt=‘QQ截图20210818113054.png’/><img src=‘/uploadfiles/image/20210818/1629257523855091256.jpg’ title=‘1629257523855091256.jpg’ alt=‘微信图片_20210818113023.jpg’/><img src=‘/uploadfiles/image/20210818/1629257502006043188.png’ title=‘1629257502006043188.png’ alt=‘微信图片_20210818113006.png’/><img src=‘/uploadfiles/image/20210818/1629257491711063198.jpg’ title=‘1629257491711063198.jpg’ alt=‘微信图片_20210818112955.jpg’/><img src=‘/uploadfiles/image/20210818/1629257479757013911.png’ title=‘1629257479757013911.png’ alt=‘QQ截图20210818113054.png’/>
